I wonder if that action had received a heavy dose of methyl alcohol before you got there.

I have the opposite issue as you David. Seems like they were aiming at zero friction. The rep levers and hammer flanges were repinned Friday...boring job. Pro felted the keybushings. Big improvement. I glued riser felts on the wippens supports to keep the hammers from flopping down into backcheck canyon and then jamming against the rocksa...I mean backchecks. All in all the sound improved, the action feels more solid. It went from 0-1 gram friction prior to my new pinning at 3 or 4 grams quite consistently for the hammer flanges. The rep lever went from a sloppy fit with a number 20 center pin and negative friction and a mushy bushing to now I have enough friction to increase the rep spring tension and prevent the jamming jack issues with a 21 1/2 center pin. Jack pinning was crap too but hey no money. And why do people use these substandard parts. Oh that's right! Now I remember. See Ron I still have brain cells. Yup...they're gen-u-whine Steinway parts.

Pinning these is like trying to shovel sand. And that is what it seems like as you repin the action, only to see it begin to flop loosely around, springs having a carnival with the rep pinning so loose, etc. I have reamed them out to the loosest allowable amount and seen some success, but a year later, there is still a few here and there that have either regained their grip, or given up the grams and are floppy loose. I think this may be one of the reasons that the WNG hard bushings will be a prime attraction for the new composite parts, never mind the stability of the flanges!

I know, alcohol/water w/ heat is the recommended approach but it produces very inconsistent results in the hammer flanges in my experience.David Lovewww.davidlovepianos.com(sent from bb) -------------- next part -------------- An HTML attachment was scrubbed...
